I keep thinking one of these days our AC unit is going to surprise us as well. But so far at least it's still working. I live in the north. So we only need AC during the summer. But during the summer the temperatures can get up to 90 to 100 degrees with dew points in the 60's & 70's. So when we need it... we need it! (I don't function well either in the heat & humidity.) I hope your family is able to get your AC problems resolved without stressing you out any more than necessary.
